Abstract
A vehicle safety device e.g. a pyrotechnic pretensioner, seat device or bonnet lifter comprises a cylinder 2 divided into first and second regions by a piston head 16. There is a gas flow connection 20, 21, 22 between the regions forming a first and second gas flow path. A slide valve element 23 is mounted on the piston rod 4 initially in a position in which both of the flow paths are open. As the piston completes its outward stroke the valve element is moved to a position in which one of the flow paths is closed. The valve element remains in this position as the piston moves back into the cylinder and the flow resistance has changed to absorb return energy and provide a favourable damping characteristic. Alternatively the one of the flow paths may comprise an annular bore in the piston between a piston sleeve (60 Fig. 11) and a piston head element 54 that is closed when the sleeve strikes an abutment at the end of travel.
